25 secondi di volo con Cy Kuckenbaker

Landings at San Diego Int Airport Nov 23, 2012 from Cy Kuckenbaker on Vimeo.

Volgere lo sguardo al cielo se abiti vicino ad un aeroporto implica costanti visioni di volo, e una familiarità con i ritmi e i percorsi del traffico aereo che il filmmaker Cy Kuckenbaker, dal suo nuovo quartiere vicino al San Diego International Airport, ha deciso di condensare nei 25 secondi in time- lapse di Landings at San Diego Int Airport Nov 23, 2012.

Uno spettacolare sciame di aerei che sfila in formazione con le nuvole, restituendo in pochi secondi una moltitudine di circa 70 aerei, messa insieme riprendendo (con una Canon 7D e EF-S 17-55 f/2.8) il traffico di atterraggi dell'aeroporto americano di venerdì 23 novembre, tra le ore 10:30 e le 15:00. Un effetto ispirato dalla controversa Flughafen, realizzata dal coreano Ho-Yeol Ryu all'eroporto tedesco di Hannover, avvistata on line, che trovate dopo il salto.

The concept is simple: shoot the individual planes flying across a pure blue sky, then chroma key the blue out as if it’s a green or blue screen leaving only the plane behind. Then put them all together on a video timeline. I did some tests and discovered that it didn’t work well if there were trees in the edges of the frame so scouting good locations took the most time. I watched the weather for a cloudless day then sat in a park and shot every plane that flew over. I locked the camera (Canon 7D with a EF-S 17-55 f/2.8) on a tripod and shot the planes with 1080p video at 24fps with an exposure I’d tested the day before (50/s, f/13, ISO 100) that would keep the sky deep blue with no blowout for a good chroma key.

To give the video a sense of temporal change as the planes fly by I did an 8 hour time-lapse under a bridge nearby shot at the same angle and composited it over the planes. Without it there’s no sense of time passing. I used an intervalometer to shoot about 800 images with the same exposure as the video. Once I had it posted as a regular video clip, I keyed the sky out of it as well. I put everything together in Adobe Premiere, which challenged my system since I needed 40 video tracks to stack all the airplane clips together. The last piece was to put a new sky back in — a still image with depth and clouds that’s panned using key frames in Premiere.

In ogni caso, Cy Kuckenbaker e HO-Yeol RYU, contribuisco a mettere a fuoco il ritmo incessante del traffico aereo che brulica nei nostri cieli, protagonista anche di questo eloquente video dei flussi aerei del pianeta.
